My 3 yr old ds started throwing up last night about midnight and then once or twice through the night. Since getting up today he has been throwing up every half hour or so- we've been giving him tiny sips of dioralyte but just seems to keep coming back. He's in bed now but still retching and boaking although nothing much more than saliva coming up. We were planning to call nhs 24 if it contines through the night. Any advice, feel so awful for him? Thanks
